HORRIBLE back pain during PMS

Jacqueline • Wife. Dog mom. Real mom. April '16 baby boy. Sept '17 baby girl.
Does anyone experience awful lower back pain a couple of days before your period? Mine is so awful that it goes down to butt cheaks and all the way down my legs! It almost feels like how people describe sciatic nerve issues. Sitting, standing, laying down, it doesn't matter. It just feels like my back is going to blow out, lol. It makes me pray that my period comes a little early so the pain can start to deminish! 
Please tell me I'm not alone!
